When continuous light 6 with energy as high as the forbidden band energy or higher is radiated locally to the semiconductor substrate 5 from the back side, photocarriers which are pairs of electrons and positive holes are generated in the interface of the insulating layer 4 and the semiconductor 5. When d. c. current bias voltage is applied to the reference electrode 3, a. c. photocurrent shows a current-voltage characteristic curve having a certain maximum peak based on the bias voltage. Since the characteristic curve is shifted corresponding to the gas concentration, the resulting body can be used as a gas sensor by examining the a. c. surfacial photovoltage generated by the photocarriers and the bias voltage dependence of the current.

Title: Elastic boundary wave device
Inventor: ITO KATSUMI
IPC: H03H9/25
Filed: 1992-09-30
Abstract: PURPOSE:To improve characteristics of an elastic boundary wave device and to attain a compact package of this device by implanting the ions at both edges of a substrate and suppressing the undesired reflected waves generated at the edges of the substrate. CONSTITUTION:Ions are implanted 4 at both the edges of one or both of substrates 1 and 2 so that the arrays of atoms are changed at both edges of the substrate and that the structure or the composition of both edges are changed. Types of these ions are not limited as long as they can change the structure or the composition of the substrate. Thus the elastic boundary waves excited by an electrode fingers 3 are not transmitted to the edge of the substrate in their modes as they are. Then undesired reflected waves generated at the edges of the substrate can be suppressed. Meanwhile wedge-shaped gaps are formed on the boundary surfaces of both the edges of both substrates 1 and 2 and then filled with an absorber. Thus the elastic boundary waves excited by the electrode fingers 3 are attenuated before they reach the edge of the substrate. So that an undesired reflected waves can be suppressed at the edge of the substrate.

IPC: B22D11/06
Filed: 1988-10-19
Abstract: PURPOSE:To decide molten metal surface position and to control casting condition by detecting temp. at each position in a mold in order while shifting temp. detecting means arranged at each block mold member together with the mold member, bringing the temp. detecting means into contact with receiver means and receiving the detected signal. CONSTITUTION:By shifting each roller 46 together with the mold member 23, the roller 46 is slidingly brought into contact with one after another of the receiver members 48 and the temp. detected signal of thermocouple 40 is transferred from the shifting side to the fixed side. These signals are inputted into a computer 52 through the detector 50. In the computer 52, conditions of shifting velocities (a), (b) of the mold, drawing velocity (c) of the cast slab and pouring velocity of the molten metal, are obtd. so that the molten metal surface becomes the fixed position based on the inputted data. Then, command corresponding to these conditions is transferred to each actuator to control the actual casting movement. As the temp. detecting means is embedded in the mold, this does not disturb a nozzle for pouring the molten metal and continuous casting is stably executed. By this method, the surface characteristic on the cast slab can be improved.
